When most people think of Seasonal Affective Disorder (SAD), they picture dark, cold days of winter. But here's the truth: SAD often starts much earlier than you realize- sometimes as soon as late summer or early fall.

Why it happens

SAD is linked to changes in daylight. As the days get shorter, even before winter officially arrives, your body begins to produce more melatonin (the sleep hormone) and less serotonin (the mood regulating chemical). This shift can leave you feeling tired, sluggish, and down-weeks before you expect it. 

Early Signs to Watch For

If  you notice these symptoms creeping in during September or October, it may be SAD starting earlier than expected: 

  • Low Engery or fatigue
  • Trouble concentrating
  • Craving for carbs and sugar
  • Sleeping more but feeling less rested
  • Loss of interest in hobbies or social activities
  • Feeling "blue" as the days shorten

Catching these signs early is key to feeling better.

Why Timing Matters

Many people wait until witner to take action, but by then symptoms may already be in full swing. Starting preventive steps in early fall can make a big difference. Just like you prepare your home for cold weather, you can prepare your mental health for the seasonal shift. 

Coping Strategies

Here are some proven ways to fight SAD before it peaks:

  • Light therapy: Using a light box daily can help reset your body's rhythm
  • Daily movement: Even short walks outdoors can boost serotonin and vitamin D. 
  • Structured routines: Keeping a regular sleep and wake schedule helps regulate mood.
  • Mindful nutrition: limiting refined cards and focusing on balanced meals can reduce engery crashes.
  • Talk therapy or medication: For moderate to severe symptoms, treatment with a provider is often the most effective option.
